Expose SMA and U.FL connectors as ptp_pins on E810-T based adapters and allow controlling them. E810-T adapters are equipped with: - 2 external bidirectional SMA connectors - 1 internal TX U.FL - 1 internal RX U.FL U.FL connectors share signal lines with the SMA connectors. The TX U.FL1 share the line with the SMA1 and the RX U.FL2 share line with the SMA2. This dependence is controlled by the ice_verify_pin_e810t. Additionally add support for the E810-T-based devices which don't use the SMA/U.FL controller. If the IO expander is not detected don't expose pins and use 2 predefined 1PPS input and output pins.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
